Difficulties with Cancelling an Existing Device Contract

I had called into the Cancellations Department (***) on February19th 2021 to cancel my device contract ***) by the end of February and had decided to retain the data contract with you guys. A representative then informed me that everything will be taken care off. I am now sitting with a bill that is due for the month of March which I am not liable to pay as I had called in February to cancel my contract. Since no payment was made for the months of March, my services are now blocked.

When the month of March commenced, I noticed that I had a pending bill due. So, I called in on the 15th of March. I spoke to a representative and they had informed me that on their side they can see I called in a month prior to cancel my contract but it was not done. I was then advised an investigation will take place and everything will rectified. I was so promised a callback from one of the line managers within the next 24-72 hours.

Since no call was made to me, I decided to phone in on multiple occasions (March 19th, 23rd, 25th), I was then informed that the matter wil be taken care off and that I will not be liable to pay any outstanding amounts since I did call in a month in advance to cancel my contract.

On March 26th, I spoke to very lovely representative who goes by the name of Mariam. She had informed me that she will escalate the matter and provided me with a reference number (1-***9230).

I have been very loyal customer to Vodacom as I have kept the same number for the past 10 year or so. I have also taken up many contracts with you guys. In total I must have taken up contracts for 5 different devices during my lengthy stay with Vodacom. And when I eventually wanted to cancel my last contract it was totally messed up by you guys. Again, I am not liable to pay the bill for the month of March as I did call in advance to cancel my contract.

Please rectify this issue as soon as possible or I may need to pursue legal action and contact an Ombudsman.
